To allwhom itmaycmicemr i I Be it known-that I, ERIK ANTON Runnnor, a subject of the of Sweden, resid- III at Stocksund, near Stockholm, in the Kingdom. of Sweden, have-invented new and useful Improvements in Internal-CombustionEng ines, of which the following is a specification, reference being. had to the orming a part hereot.

This invention relates to. internal combustion engines.

In order to increase or decrease the supply of fiiel in an internal combustion engine it is. custom to, adjust the; distance between the fuel pump. and the reciprocating part actuating the said. pump. The said ad ustment is usually performed by means of ascrew or the like situated at the ump. Sacha device has however several draw acks. For one. thin it is dificult to obtain a quite accurate ad'ent, and for theother' the adjustment is liable to be disturbed during the running. of the motor.

The ob'ect of the invention is to provide an. adjusting device which works in all respects quite satisfactorily.

The invention consists, chiefly, in that the pump: d the movable member operating the same arebothcarried by a support adjustable relatively to the part of t e engine from a a; vement is imparted to the mber operating the Thus the stroke at the pump and, t ere y, the supply ct fuelmay be varied. by changing the relative osition of the said support. and the move 1'" part connected to the p ump-operating member. By this means not only can the adjustment be performed with the greatest accuracy but me. parts y also be so reliahly secured in position that the suply of heel: cannot unintentionally change i the-we. of we. I

The invention is articularlyot enortsnce ininternal con ustion enginesin w 1. oh the reciprocatory pump-operating member coiiperates with a broken guiding surface tor ea the speed. at the engine, in.- asmucli as in s case the said giidi suriaoe may be .ed. by the eferemid. support iiar the pump and the pumproperating member; By this means-the sa? iding surface will always have a ed position. relatively tothe pump, by whichthe speed. of theiengine constant.

In the drawing I have shown a suitable embodiment of my improved regulating device applied to an internal combustion engine. Figure 1 shows the regulating device adapted to be operated by hand, and Fig. 2

shows the same connected to driven by the en 'ne.

Referring to t e drawings, a is a disk a governor which may be of circular or other suitable form. Attached to the said disk are the pump 5, the'fulcrum'c for the reciprocating weight at actuating the pump, and, in the case illustrated in Fig. 1, the plane or guide 6 servin to control the speed by causing the weig 't d toswing outwardly so as not 'tomeet the pump iston y when the speed is increased above t 'e normal one. The invention is not limited to the'use of aspeed lane, but instead of such a plane a straight sliding surface 6 for the part d may be employed, as shown in Fig. 2, or the said part. may be guided or-suprted otherwise, if referred. it willthus a seen that the dis a may be turned or otherwise adjusted without the relative positions of the arts 5, 0, e being changed. On the other 2 disk (1 for instance aturning' of the said disk about the pin 9', will cause a change and, an adjustment of the of the relative positions of the reciprocating weight d or an angle lever 71., or the like, connected to the said weight, and the part of the engine, for instance the shaft 2', from which movement is transmitted to the said weight. By this means the stroke of the pump ma be increased or decreased, as may be esired. Thus, if the dlsk a is turned 'n the counter-clockwise direction, the stroke is decreased, and vice versa. A s is easily understood, the angle of turning 13 in each case very small, and the supply and exhaust conduits m and n connecte to the limp-therefore need only be slightly ii'exi- El'e in order not to prevent the turning.

It is obviousthat, ifpreferred, the disk or part a may be stationary in whichcase the part i ma be adjustable. in either case the intermediate motion transmitting {part or parts may be adjustable in length i: desired. Thus for instance, the eccentric rod d5 interposed between the shaft 2' and. the an le lever h ma be made in twe. parts ad ustabl'e. relative y to each other by means of a rightand lefthand threaded nut Z.

by means of a handspike other easily manageable vno hit and miss regulation, such as the broken plane e shown in Fig. 1. In such case the parts mentioned form a speed gov:

ernor varying the supply of fuel by adjusting the dis a.

Obviously-the regulating device described may be used whether the pump be employed for pumping liquid fue or other liquid,

such as water.

Having now described my inventionwhat I claim and desire to secure by Letters Patent is:
